Question
Which of the following sets correctly classifies $CH_4$, $NH_3$, and $B_2H_6$ respectively based on their molecular hydride type?
Answer: B
💡 Solution & Explanation
$CH_4$ (Group 14) has exact electrons for conventional Lewis structure, making it electron-precise. $NH_3$ (Group 15) has a lone pair, making it electron-rich. $B_2H_6$ (Group 13) has insufficient electrons for standard 2c-2e bonds, making it electron-deficient.
